Title: Bidirectional communication system and its central information communication controller and terminal communication controller
Inventor: KAMURA KOICHIRO
IPC: H04N7/173
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To suppress reduction of system performance and to maintain high stability even when a communication controller continuously transmitting a signal exists or a high traffic load is inputted to a system. SOLUTION: A central information communication controller 1 detects a packet reception success rate on an up trasmission line, and when the success rate is smaller than a threshold α, generates transmission rule level information for reducing the transmission probability of a communication controller and notifies the generated information to respective communication controllers 2a to 2c through a down transmission line. Each of the controllers 2a to 2c generates a random number based upon the notified transmission rule level information and judges whether transmission is to be started or not by referring to the random number.  At the time of judging the postponement of transmission, each communication controller waits until the reception of 'transmission permission' from the controller 1, and at the time of receiving the 'transmission permission', starts the transmission of user data.

Title: Displacement converter
Inventor: ONO YUTAKA
IPC: G01D5/244
Filed: 1983-10-04
Abstract: PURPOSE:To obtain a displacement converter, which does not have errors and phase fitter due to delay in a circuit system and does not require adjustment, by detecting light transmitted through a code plate by a specified image sensor, counting the detected signal by a counter through a bandpass filter, and processing the result. CONSTITUTION:Image sensor 4 is driven by a reference clock fc and detects light transmitted through a code plate. The detected signal undergoes phase modulation through a bandpass filter 6. A signal e6 becomes a rectangular wave signal e7 through a wave shaping circuit 51 of a phase measuring means 50. The signal e7 is inputted to the D terminal of an FF52, which receives the reference clock fc as a clock input. An output e8 of the FF52 is inputted to a control circuit 53. A pulse e9 is generated at every cycle of the signal e7 and inputted to a counter 54. The clocks fc of the one cycle are counted. Output D1 of the counter is inputted to an operation circuit 55, where operation is performed. Then the output corresponding to the change in the code plate can be obtained. Since the signal e8 is synchronized with the clock fc, errors are not computed.
